摘要：
The domain morphology of four different types of thermoplastic elastomers in polycarbonate was studied. The domain shape, size, and its distribution were found to depend on the type of the elastomer and the solvent used for film preparation. A qualitative reasoning, based on solubility parameters, is presented to account for the differences in the morphology of these domains. Stretching the films leads to deformation of the elastomer domains, which again depends on its type, and the solvent used for film casting. Correlation between the change in the mechanical properties of polycarbonate and the domain morphology is presented. In addition, the effect of domain size and the elastomer type on the calculated abrasion resistance is discussed.
